ENVELOP- Specification of Letters Patent.

Patpnted July 3, 1906...

Original application filed llovember 8 1904, Serial No. 231.886. Divided and this application filed January 17, 1905. Serial To all whom itmay concern:

Be it known that 1, MAX M. Conn,- a citi-' zen ofthe United States, residing in the city and county of San Francisco and State of California, have invented new and useful Improvements in Envelops, of Which the follow a transparent space or window in its face through which the name and address on an inclosure may show through.

The object of this invention is to so design T5 the window-opening and to associate with said window such descriptive matter as will offer novel and unique possibilities for advertising.

The invention consists of the parts and the construction .and combination of parts, as hereinafter more fully described and claimed, having reference to the accompanying drawings, in which Figures 1 and 2. show my invention in its application to specific brands of goods.

In carrying out my invention I take a I blank sheet of paper or an envelop-blank of suitable strength and texture which is, say, semitransparent and apply to a portion of 0 one side of the blank, generally on the inside,

a preparation which has the property of rendering transparent the portion to which it is applied. The remaining portion or a art of the remaining portion of the blank W 'ch 3 5 forms the face of the finished envelop A is then imprinted with a suitable opaque colorin -matter.

employ a compound or preparation, such as paraffin-oil and resin or a rease, which 40 produces the desired result 0% renderin a semitransparent paper transparent. T is preparation is stamped or printed on or otherwise applied to the blank to provide the transparencyor Window of the desired design, and it is applied to such part of the blank where the transparency is desired to appear on the face of the envelop, and it may cover a larger or a lesser space, according to the desired size of the transparency or window.

Since the oily preparation has a tendency to creep or bleed beyond the borders of the space imprinted by the stamp or die by which it is applied,-and so ossibly stain or 5 5 discolor the rest of the enve op or give a ragged appearance to the window-opening, it is preferred, even where the paper might ordinarily be deemed sufliciently opaque, to apply some sort of coloring-matter at least around the immediate borders of the trans- 6o parency. This coloring-matter may be applied solid over the face of the envelop, or it may take the form of graduated tints or of being shaded, or the representation of a surrounding border, or cloud effect, as indicated 6 5. at 3 in Fig. 1.

i In any event the effect and object of this colored border are to give a definition to the window-opening and obliterate or cover up the otherwise rough unfinished outline of the window resulting from the encroachments of the oil or grease or other substance beyond its desired limits.

Usually and perhaps preferably the preparatioii and coloring-matter are applied on opposite sides of the blank, the preparation on the inside and the coloring on the outside. Developing out of this idea of making an unpunctured envelop with a window or transparency for the addressees name to appear through is the idea of changing the form or outline of this transparency to correspond with the trade-mark, desi n, or advertised object of a merchant, manuTacturer, advertiser, or other person, company, or firm.

Fig. 1 shows a transparency in the shape of a cucumber, the trade-mark of a wellknown manufacturer of a great many varieties of goods.

Fig. 2 shows a cigar in transparency and the Words Blanco cigar in non-transparency on colored opaque field. The number of shapes this trans arency may take is almost limitless. Di erent peo le might use an envelop with a Window in t e shape of an 5 oyster, a fish, a cake of soap, and other toilet articles, a cascaret, a dress-shield, a biscuit, an article of hardware, and other articles of manufacture, and so on indefinitely, having due regard for the necessary size of the tran's- 10o parency, so as not in any way to interfere with the clear showing up of the addressees name inside. The essential feature in this connection is a'window which in general outline is characteristic of a symbol of trade. By symbol of trade? is meant any design suchas mentioned above or trade-mar characteristic of certain goods or the product of a certain manufactory.

When the window-opening is formed by no the application ofa grease or equivalent comsame time inexpensive and effective advertising medium. Every one needs envelops.

These advertising-envelops can be made atsmall expense. They can be made of any shape or size and made to fit the stationery rather than the stationery made to fit the envelop. They can be used not only for mailing, but for sendin it out circulars and the like by messenger. he characteristicallyshaped window and the associated letters and colored background constitute a most striking advertisement to attract public attention, the object of all advertising. I do not wish, however to limit myself in the application of this idea of an envelop having a window which in outline is characteristic of a symbol of trade to envelops made originally from non-transparent stock, as above described, for I may employ a transparent stock and form the Window-opening by printing with or otherwise ap lying opaque coloring-matter'to a portion 0 the envelop.

Generally the Window-opening by itself alone and unassociated with any descriptive an essential feature matter or words formin of the trade-mark W0 ul. have very little significance as referring to a particular manufacturer. For instance, a window in theoutline of a bolt might refer to many bolt 1nanufacturers, or a Window in the shape of a cigar unassociated with a trade-name would be meaningless; "but when there is associated with the window-opening of characteristic or peculiar deslgn a trade-name or some word or words usually associated with or relating to the pictorial feature every one seeing the envelop is confronted with a strikinga vereaaeos and address on the inelosure to show through,

protects the writing thereon, and obviates the necessity for an address on the exterior of the envelop. r 1

Having thus described my invention, What I claim, and desire to secure by Letters Patent, is

1. An advertising device comprising an envelop having a Window through which the addressees name on an inclosnre may show through, said window being in outline characteristic of some symbol of trade, a tinted or colored border surrounding and giving definition to said window and permanent advertising matter forming no part of the address,'appearing 'on said tinted border, and related to and in juxtaposition with the outline of said Window. 4

2. As an advertising device, an envelop having a generally opaque face except for a transparent window portiort through which an addressees name on an inclosure may show through, said Window being in general outline characteristic of a symbol of trade,

and permanent printed matter on the face of the envelop related to and in juxtaposition With the outline of the Window and cooperating With'said outline to indicate a particular brand of goods. Y

In testimony whereof I have hereunto set my hand in presence of two subscribing Witnesses.
